Description

一种低压损直通式截止阀
技术领域
本发明涉及智能仪表阀门技术领域,具体涉及一种低压损直通式截止阀。
背景技术
在智能仪表行业中,如智能水表、燃气表等领域,现有的截止阀都不是直通式的,比如装在燃气表进气口的阀门,阀体进气口和出气口呈90度,或者是阀瓣正对着进气方向,而装在燃气表出气口的阀门,从外部看,虽然进出气口呈180度,但在阀体内部,是经过了两个90度的转弯的。这种结构的阀门的进口和出口的压损都比较大,而且阀门成本也比较高,造成资源的浪费和经济效益的降低。
发明内容
针对现有技术中存在的技术问题,本发明提供了一种低压损直通式截止阀,具体技术方案如下:
一种低压损直通式截止阀,设置于流道上,包括阀瓣、阀杆和阀口,所述阀瓣用于打开和关闭所述阀口,所述阀瓣与所述阀杆呈一定角度,所述流道上的进气口和出气口直通。
进一步的,所述阀瓣与所述阀杆呈45°角,所述阀杆垂直于流道。
进一步的,所述流道上的进气口和出气口直通。
进一步的,所述阀杆与阀瓣通过销子活动连接。确保关阀时阀瓣到达阀口后,自动调节,压紧阀口。
进一步的,还包括传动机构,所述传动机构带动阀杆作往复直线运动。
进一步的,所述阀瓣包括阀瓣下压板和阀瓣上压板,所述阀瓣下压板和阀瓣上压板中间压紧中间的阀瓣橡胶板,关阀到位时,阀瓣橡胶板与阀口压紧。确保阀瓣完全压住阀口,防止内泄漏。
进一步的,所述低压损直通式截止阀为进气口阀,包括阀体本体和进气接管,进气接管上设有进气接管卡扣,两者通过进气接管卡扣插入阀门本体的卡座连接。安装方便,针对不同的燃气表,只需更换进气接管即可适配,阀体本体无需变动。只有进气接管,没有出气接管,且阀体本体更简单。
进一步的,所述低压损直通式截止阀为出气口阀,除有阀体本体、进气接管外,还增加出气接管,出气接管和阀体本体通过螺丝连接固定。针对不同的燃气表,只需更换出气接管即可适配,阀体本体无需变动。
进一步的,所述低压损直通式截止阀安装于燃气表内进气口的下部。
进一步的,所述低压损直通式截止阀安装于燃气表内出气口的下部。
本发明的低压损直通式截止阀,阀杆与阀瓣呈45°角,阀口平行于阀瓣,所述阀杆垂直于流道,极大地降低了阀门的压损和成本,而且功能可靠,生产成本低。

具体实施方式
下面结合说明书附图,对本发明的技术方案做进一步描述。
如图1和2所示,本发明的低压损直通式截止阀,包括传动机构1,传动机构1输入直流电后,带动阀杆2作往复直线运动,完成开关阀门,比如传动机构上安装齿轮,阀杆2设置齿条,齿轮和齿条啮合,由齿轮带动齿条作往复直线运动。阀杆2与阀瓣4呈45°角,通过销子8活动连接,阀瓣4的上下别为阀瓣下压板10和阀瓣上压板11,阀瓣下压板10和阀瓣上压板11为塑料材质,两者压紧中间的阀瓣橡胶板9,三者通过螺丝紧固连接。阀瓣4与阀口7平行,开阀时,阀杆2向上直线运动,离开阀口7,完成开阀,关阀时,阀杆2向下直线运动,直到阀瓣4压紧阀口7,完成关阀。在整个开阀和关阀过程中,阀杆2始终垂直于流体运动方向,且与阀瓣4及阀口7呈45°角。关阀到位时,阀瓣橡胶板9与阀口7压紧。阀瓣直径大于阀口直径。
如图1所示的低压损直通式截止阀为进气口阀,包括阀体本体6和进气接管3,两者通过进气接管3上的四个进气接管卡扣12插入阀门本体6的卡座连接。如图2所示的低压损直通式截止阀为出气口阀,除有阀体本体6、进气接管3外,还增加出气接管5,出气接管5和阀体本体6通过螺丝连接固定。
如图3所示,根据燃气表的内部结构,该低压损直通式截止阀安装于燃气表内进气口13的下部,气体经阀口7后进入燃气表机芯15,再从出气口14出气。
如图4所示,根据燃气表的内部结构,该低压损直通式截止阀安装于燃气表内出气口14的下部,进气接管3与机芯15连接,出气接管5和出气口14连接,气体经进气口13进入燃气表机芯15,先经过该低压损直通式截止阀,再从出气口14出气。
采用本发明的进气口阀门,在6m3/h流量点压力损失约为30Pa左右,而常规进气口截止阀的压力损失约为40Pa左右。采用本发明的出气口阀门,在6m3/h流量点压力损失约为40Pa左右,而常规出气口截止阀的压力损失为60Pa左右。两相比较,采用本发明阀门,有效地减少了能源的损耗。
